Beauty's Demise

Elyse Ashmore [13], Elle Courtser [16], Andrew Coldéire [15], and Luke Roben [16], all were normal teens.. but, they were dead. Elyse commited suicide, Elle was shot in the Virginia Tech shooting, Luke died in a car crash trying to get to the hospital, to see his mom, and Andrew died from a blow to the head. They didn't have the BEST lives. But when they're brought back to life by 'Miss Misery' to exterminate 'parasites' - people who wreck havoc to others lives, killing everything - they agree. They are granted immortality, and they begin their hunt. Having been awoken after an apocolypse, not many human lifeforms were found.. can they fix this mess?
